You beat me to it. I am curious now. Like the OP stated it probably wouldn't make any difference. I would like to see a XPg vs XP-G2 with 18650 side by side. Keith

Look here. Top of the page has a MG P-rocket xpg straight swap to xpg2. Second page I post up the same data on an s-mini and a fenix LD01. No beamshots though....still been too dang warm outside at night.

not sure if xpg vs xpg2 would really make a difference as far as output with 1aa... even if its 25% brighter... 125 lumens vs 100 maybe?? still has anyone seen any offerings in budget lights yet? ive seen foursevens is offering a few but $62 for a single aa? NO.

I’m still waiting for a nice XP-G2 P60 Drop In, wether it is from SF or UF or someone else, I really love the beam profile of the old XP-G (+ OP reflector) and would love to see the new XP-G in a similar setup.

I hope it doesn’t takes the manufacturers too long do produce a nicely driven drop in.

The mini is a great choice. I picked the preon just cause I have the hi cri and coolwhite to compare.

For brightness differences, there’s no chart per say but some good info if you look up magnetic control ring lights. Quality infinitely variable lights step up in a fashion that’s noticeable to the eye… Which if I remember right is roughly 40% increases in brightness to be visible to the eye

i know that the difference between 360 and 650 lumens from my zebra (i believe those numbers) isn’t THAT big in real life
but side by side you should be able to see the difference between xp-g and xp-g2 (mainly in throw)

The xpg2 has a tighter beam profile, better efficiancy and I would call 125/100 lumens, 1/4 more so 25% brighter. Am I wrong?

What Boaz is referring to is the fact that it takes quadruple the lumens for your brain to perceive double the brightness.

Ah yes, that I knew

Yeah i think this is where lots of people just get confused on flashlights .It seems people shop according to specs and boys being boys think that bigger is better .So now we have chinese vendors lying to people who miss the fact that there is virtually zero difference between a 800 lumen light and a 500 lumen light .

I proved this to myself a long time ago when I took 7 Tank 566's and rubberbanded them all together in a Chunk -O-Light.

Clicking each 170 lumen light on one after another proved to me that ..

Two wasn't twice as bright as one ...

and with each click ..adding 170 lumens ..nothing very exciting was happening very quickly .. each added light didn't add much light to the beam .

but a +1000 lumen light 2 years ago seemed pretty impressive to a noob like me .

What infinite variable lights are out in XP-G2?

I don’t know of any yet. But I may send a Sunwayman off to my favorite modder to get one as it’ll be months before we see anything. Ualnosaj might be able to pull off a limited run batch should I ask him?

Perceived brightness is dependent on how you are using the light. If you’re shining the light at a wall 3 feet away, the reflected light will affect the eye, so the brighter light doesn’t look all that much brighter. I kinda did this purposely with the drivers I asked JonnyC to reprogram for me. I wanted 100-60-20% modes. At close range, the 100 % does not look dramatically brighter than the 60%. This was my goal. I can see very well out to 100 yards at 60%. This is including the spill. Where the difference in brightness shows up is at the extreme range of the light, where the reflected light is not shutting down your eyes. At, say, 150 yards, the difference between 100 and 60 is very apparent. What I have, in effect, is a light (at 2.8 Amps) that has three modes, medium-high-turbo. The lowest mode being 33% of the next highest mode duplicates the mode spread between medium and high with the Nanjg driver. Instead of having a low that is too low to have much utility outside, I have a turbo that throws an amazing distance, for a P60. Lotta bang for the buck with this setup!

How does this theory apply to neutrals. I just ordered a neutral thrower with lesser lumens than the cool white. Will there be any perceived difference? Will the neutral actually let me to see more? What differences will my eyes see?
I’ve seen some discussions about this somewhere, but I’ll have to admit I didn’t really understand it all.

Depth perception with neutral and especially High CRI is a lot better than with cool white lights and outside in nature the most rare color is blue... so a lot of the high power blue light gets rather absorbed than reflected back.
